Britain England, a company of .Great Application January 7,liididserialNo. 517,457. I In Great Britain January13, 1943 j 2 Claims.1 101. 57-59)? This invention relates to wire stranding machines of thehigh speed tubular type in which the wire reels are mounted within arevolving tube built upfrom a number of sections. More particularly thisinvention relates to the construction of machine described and claimedin prior Specification No. 2,218,278 in which there is a roller bearingassembly for the revolving tube, such assembly comprising anintermediate runner ring which surrounds the adjacent ends of twosections of the tube to which the ring is secured. In the said priorconstruction, the web of the intermediate runner ring is bolted tointernal flanges of the adjacent sections of the tube.

The latter is usually bored, and turned and cut away at various pointstogive access to the interior of the tube. The cutting away of the tubeleads to distortion which creates difiiculty in fitting and assemblingthe various parts which depend upon the accuracy of the tube bore andexterior.

The object of my present invention is to prevent the setting up of heavystresses in the tube during its movements such as will result inrelatively rapid fatigue and fracture thereof. A further object of myinvention is to make the machine stronger, more silent and reliable inservice and capable of being run at. higher speeds than at presentusual.

The invention consists in a wire stranding machine of the type specifiedin which there is a roller bearing assembly for the ends of therevolving tubes which come adjacent to one another comprising, incombination, a runner ring (for the said roller bearing assembly) withan internal web projecting inwards between the adjacent ends of twotubes, the runner ring being clear of the exterior of the tubes, twodisc like parts with projections at one side each of which comes withinand is secured in the end of a tube, parts of each disc projecting overthe end of the tube-to form an abutment between the tube and the web ofthe runner ring, rubber bushes secured to outer and inner metal sleeveslocated in holes in the runner ring, and bolts securing alternate innersleeves to a disc in 'the end of one tube and the other sleeves to thedisc in the end of the other tube.

Referring to the accompanying explanatory drawings:

Figure Figure 2. Figure 4' is a cross sectional view on the line 4-4 ofFigure 1 drawn to a larger scale.

Figure 5 is an end view of one of the discs at- 1 which has a flangelike projection d at two points bywhich it is secured by riveting orotherwise in the ends of the two tubes e and f to be connected together.Parts .0 of the discs 0 between the flanges d project beyond the ends ofthe tubes e and Land in conjunction with the means for securing theinternal web to the discs act as yielding abutments forithe tube ends.The discs, which are larger in diameter than the tubes, are

after being secured in position, turned true on the outer diameterandact as the true guide for boring and facing all the discs in position.The outer diameter of the discs 0 is slightly rounded so as to be freetoallow the slight articulation movements for which the rubber bushes areprovided. y

Within the internal web b are holes into which fit rubber bushes gsecured to internal and external metal sleeves h and i, the internalsleeves being longer than the external ones and projecting beyondthe-rubber bushes. Alternate rubber V bushes are bolted to the disc c inthe end of one tube, as e, and the other rubber bushes are bolted to thedisc in the other tube. The bolt :i at the upper art of Figure 3 holdsthe internal sleeve'h nal rib b which obviate fracture and fatigue ofthe .tubes 6 and f where they are connected to the discs 0.

The tubes e: and f are solid drawn steel tubes I which are not bored andturned but are faced at Figure 1 is a-longitudinal sectional elevationof their opposite ends and cut away at m to give access to theirinteriors for placing the bobbins as n and other parts in and removingthem from position in the tube.

Secured in the tubes at intervals to suit the cradles o and theirhousings p are disc like parts q, each of which has part cylindricalflanges rprojecting from one side into which studs or The rubber bushesg which are secured to the internal and external sleeves h and 2 allowor limited relative movements between the discs and the interrivetspassing through the tube are secured to hold the disc in place. Holes 5are for the .passage of the wire in the usual manner.

When the discs q have been secured in place in the tubes they are boredand faced at one setting to receive the cradle housings p. This ensuresthat all the housings are aiially in line. The cradles 'o are thensupported in the usual ball or roller hearings in the housings. It willbe appree ciated-that the cradles o are weighted so theftthey do notturn as the tubesaevom. I

What I claim is:

1. In a wire stranding machine of the .type

specified in which there is archer bearing assembly for the ends of therevolving tubes which come adjacent to one another, in combination, arunner ring for the said roller bearing assembly with an internal webprojecting inwards between the adjacent ends of two tubes, the runnerring being clear of the exterior of the tubes, two disc like parts "withprojections "at one side each of which comes within and is secured inthe end of a tube, parts of each disc projecting over the end of thetube to form an abutment between the tube and the web of the runnerring, outer and inner metal sleeves located coaxially in holes in therunner ring, rubber bushes secured to said outer and inner sleeves, andJoolts securing alternate inner sleeves to a disc in the end of one tubeand ,the other sleeves to the disc in the end of the other tube.
